We are a professional company providing sodium feldspar . We have been committed to the Las Vegas industry for many years and have achieved great results. We have been endorsed by our customers. The company operates albite, which is reasonably priced, reliable, and high in technology. This has enabled the company to have a good brand image in a short period of time and laid a solid foundation for the company's long-term development. Here are some notes on sodium feldspar firing ceramics:
1. The feldspar melts and grows the stone glass at high temperature, fills the particles between the green body, and dissolves other minerals, such as kaolinite, quartz, etc., to make the body dense, which helps to improve the mechanical strength and electrical properties of the product. And translucency.
2. Requirements for feldspar in ceramic production:
a, wherein the content of K2O and Na2O is as high as possible, and the content of the colored oxides Fe2O3 and TiO2 is as low as possible;
b, the content of SiO2 should be 63% -68%, the content of Ali2O3 should be in the range of 17%-23%;
c, the content of CaO in feldspar should not be too high, if the content is too high, it is easy to reduce the sintering temperature for the blank, and the glaze affects the fluidity of the glaze.
3. Before sintering, feldspar and quartz are non-plastic materials, which can shorten the drying time of the body and reduce drying shrinkage and deformation.
4. Sodium feldspar has a greater effect on lowering the glaze firing temperature than potassium feldspar, and can improve the translucency of the product, but the firing temperature range is not K-feldspar width.
5, feldspar is the main flux raw material in the glaze, such as feldspar porcelain, feldspar accounted for about 25% in the body, accounting for about 50% in the glaze, the main role is to reduce the glaze firing temperature.
The company's aim is to provide users with excellent products, quality services, advance in the development, improve in development. Welcome friends from all walks of life to come to the factory for consultation, negotiation and guidance, willing to cooperate sincerely with you!
